Relays Triggering Commands
The AC relays in the power supply are triggered when the TV-SUB-ON command (3.2V)
is output from the A board.
Note: The PANEL-MAIN-ON command (3.2V) from the D board can also trigger the
relays, but since it’s preceded by TV-SUB-ON, it has not effect on the relays because by
the time this command is output, the relays are already energized.
